Distortion of the racket when stringing crosses more than 1 lbs lower than mains

I have a dropweight stringing machine. If I string my crosses more than 1 lbs lower than my mains, I get a huge distortion in my frame (about 1,5 inches wider). This applies to all frames I string, and I have strung a lot of them. I had this distortion in the first two rackets I stung with the crosses more than 1 lbs lower, and I ended up cutting the strings out because it affected the playability of my racket.

Can anybody tell me why many people string their crosses 2 lbs or more lower? Is it just me who gets this distortion?

you mean my 6 point mount system not tight enough? I know for sure I don't mount my rackets too tight. I always leave a very small margin, so my mounts just don't touch the racket. This margin is barely visible with the eye, only if you look at it closely. Can this cause my problem?

When you mount your racquet and grab the handle and shake it back and forth, you shouldn't have any rattles or anything like that. It should be so snug to the mount that the mount just moves with the racquet as one piece. Mount it just tight enough for that but not any tighter.

Unless you mounted the frame 0.75" away from the support that isn't your problem. I think your standard are moving. You make it sound like this only happens when you have a 1 lb difference in crosses and mains. I find that hard to understand is the standards are not moving.

That's way too much distortion. When I string Babolat pure storm racquets there is no measurable difference in racquet shape when the crosses and mains are at different tensions...Haven't deviated a lot, but a few pounds. When I mount, all mounting points touch and are snug to the racquet. No play/movement.

Sorry guys, I am from Europe and I made a mistake when I converted from cm to inches. It is actually 0,15 inches distortion. This affected the playability of my racket big time. This happens when I string my crosses more than 1 lbs less than my mains. Therefore I always string my crosses at the same tension or 1 lbs higher (I never tried a higher difference for my crosses) than my mains. Then the distortion is 0,06 inches (wider) and my racket plays fine.

Irvin, I am not sure if your post still applies, now you know the distortion is less than I previously said, but I am sure my standards (you mean both 'arms' of my stringmachine I presume?) are secured.
